UNS 90S - 47.9 Gallon Ultra Clear Rimless Aquarium
Product Overview
The UNS 90S 47.9 Gallon Ultra Clear Rimless Aquarium provides an expansive, master-scale shallow canvas. Belonging to the specialized "S" (Shallow) series, the 90S prioritizes wide horizontal space and generous front-to-back depth (22.05") over traditional vertical height. This large shallow aquarium delivers maximum light penetration, a unique top-down viewing experience, and an open layout ideal for sweeping Iwagumi stone scapes, shallow nature ponds, or hybrid paludariums with emergent hardscape and plant growth.
Key Features & Benefits
-
91% Diamant Ultra-Clear Glass: Premium low-iron glass eliminates the green tint found in standard aquariums for true-to-life color accuracy.
-
45° Mitered Edges & German Silicone: Precision-cut 45-degree mitered joints double the bonding surface area for high-performance German clear silicone, forming stronger seams.
- Shallow Panoramic Proportions: The 35.43" length paired with a low 14.17" height offers intense PAR light penetration to grow demanding carpeting plants easily while providing a dramatic "pond-style" top-down perspective.
- Expansive Golden Ratio Depth: Features a generous 22.05" width, giving aquascapers essential room to build complex hardscape perspective, substrate slopes, and multi-layered plant arrangements.
- Signature Laser-Etched Branding: Features a clean, laser-etched UNS logo in the glass corner for an authentic, museum-quality finish that will not peel or fade.
- Acoustic Leveling Mat Included: Includes a pre-cut dense foam leveling mat to absorb micro-vibrations, level minor surface imperfections, and prevent structural stress cracks under heavy load.

Frequently Asked Questions
1. Why select a 90S shallow aquarium over a standard 90P or 90U tank?
Shallow aquariums prioritize horizontal footprint over height. The low-profile 14.17" height of the UNS 90S delivers superior PAR light efficiency for demanding carpet plants while allowing hardscape wood and emergent plants to breach the water surface for a striking open-top display.
3. Why is a leveling mat mandatory for rimless aquariums?
A filled 47.9-gallon aquarium weighs over 450 lbs when accounting for water, rockwork, and substrate. Because rimless glass tanks rest directly on their bottom panel without a raised plastic perimeter frame, even microscopic debris or sand grains on a stand can create concentrated stress points under that weight. The included dense foam mat absorbs micro-imperfections and distributes weight evenly across the entire footprint to prevent glass stress cracks.
